UK's largest nuclear power station Sizewell B placed on standby due to nearby wildfire

On July 30, the UK's largest nuclear power station, Sizewell B, was placed on "standby" status due to a heathland fire at Dunwich Heath, less than 5 kilometers from the plant site. There is currently no risk of the fire spreading toward the facility given wind direction. EDF stated it is "continuously monitoring, with no threat to facility safety," but approximately 120 firefighters and 18 fire engines were deployed to tackle the blaze in the Liston area. Suffolk Fire Service assessed the fire as "active and changing," warning it could last two days, with hundreds of homes evacuated. Suffolk Fire Service warned the fire is expected to last two days and described it as an active and evolving situation. Hundreds of properties have been evacuated as firefighters continue to battle the raging forest fire. Experts noted...

UK Interim Report on Fission Materials Roadmap Highlights New-Generation Nuclear R&D Priorities

The UK National Nuclear Laboratory (UKNNL) and the Henry Royce Institute recently released the "UK Fission Materials Roadmap Interim Report." The report states that the UK needs to clarify as soon as possible the priority technology routes and operating environments for next-generation nuclear reactors, so as to concentrate materials research resources on key directions and support future nuclear power development. The report argues that the UK should decide within the next one to two years whether to build a domestic materials test reactor; within the next five years, the government should also establish a national materials archive to preserve irreplaceable irradiated material samples. The report also recommends making long-term funding commitments of at least five years for relevant research projects...

Third fuel debris retrieval test at Fukushima Daiichi Unit 2 postponed due to robotic arm malfunction

The robot used by Tokyo Electric Power Company (TEPCO) for the third experimental fuel debris retrieval at Fukushima Daiichi Nuclear Power Station Unit 2 malfunctioned during an on-site operational test, forcing the cancellation of the plan originally scheduled to start after July 2026 if all went well. The company stated it will reassess the relevant procedures. The malfunction occurred in part of the large robotic arm equipment used to collect fuel debris. During an operational test in the reactor building of Unit 2, TEPCO found an abnormality in one of the motors driving the robotic arm, causing the brake to fail to release and the arm to be unable to extend. The company is currently studying the replacement of the faulty motor. The third experimental retrieval plan was to use a large robotic arm...

UK to Invest £8.4 Billion in Dreadnought-Class Nuclear Submarine Program

The UK Prime Minister's Office stated that the UK will announce an investment of £8.4 billion (over $11 billion) for the construction of four Dreadnought-class nuclear submarines, thereby launching the fourth phase of this submarine program. According to the relevant press release, this investment will be used to strengthen the UK's nuclear capability building and advance the continued implementation of the Dreadnought-class submarine project. Under the framework of the new phase, the first of the four nuclear submarines is expected to complete sea trials in the early 2030s and enter service with the Royal Navy. The UK Ministry of Defence previously released a long-term defense budget for the next four years at the end of June, planning to invest nearly £300 billion (approximately $400 billion) in various areas of the military-industrial complex. Data shows that £4.7 billion of this funding has yet to be secured, with specific funding sources to be determined in the autumn budget.

Fuel unloading completed for Unit 3 of Dukovany Nuclear Power Plant

On July 30, Unit 3 of the Dukovany Nuclear Power Plant completed the unloading of reactor fuel assemblies, and the planned refueling outage has now entered its next phase. During this outage, the plant will replace part of the nuclear fuel and carry out hundreds of inspections, tests, and maintenance activities to enhance nuclear safety levels and ensure the long-term stable operation of the unit. In this outage, although the actual number of fuel assemblies to be replaced accounts for about one-fifth of the total, operators must first remove all fuel assemblies from the entire core and transfer them to the spent fuel pool. Subsequently, the reactor water level will be lowered to create conditions for maintenance of core cooling system components and inspection of some primary circuit equipment...

TEPCO says cooling interruption of spent fuel pool at Fukushima Daini Unit 1 due to human error

Tokyo Electric Power Company (TEPCO) announced on July 29 that the event in April 2026, where the spent fuel pool cooling system at Unit 1 of the Fukushima Daini Nuclear Power Plant was shut down for approximately 32 hours, was determined to be caused by human error. At the time of the incident, the plant was in the decommissioning phase. On April 5, a fault alarm was triggered by the cooling water circulation pump of Unit 1 at Fukushima Daini. After on-site personnel confirmed smoke from the equipment, the pump was stopped, resulting in an interruption of the spent fuel pool cooling system for about 32 hours. TEPCO previously stated that the cause was damage to the cable connecting the pump motor. According to TEPCO's latest explanation, the cable melting may be related to the installation method when the cable was replaced in 2012...
